Fixtures, Fixtures for Lamps, and Lamps

technical field

The present application relates to the field of lamps, and in particular, to a fixing seat, a lamp fixing device and a lamp.

Background technique

Lighting is an indispensable electrical appliance in people's daily life. Traditional lamps and lanterns are usually fixed to the foundation through their different mounting chassis. The structure and size of the mounting chassis of different manufacturers and different types of lamps are different. Drill the corresponding holes and install and fix them with bolts, expansion screws, etc., and wire them separately. When a new lamp needs to be replaced, it is often necessary to replace the installation chassis and wiring, and the installation method is very cumbersome.

In order to simplify the maintenance and replacement of lamps and lanterns, lamps with unified lamp fixtures appear on the market one after another. The lamp fixtures in such lamps are usually divided into two parts, and one part is used for fixing on the foundation, which can be called The fixed seat, and the other part is fixedly connected with the lamp body, which can be called a connecting seat.

After the fixing base is fixed on the foundation, the fixing base can be quickly and easily mechanically fixed and electrically connected with the connecting base, thereby greatly simplifying the installation process of the lamp. Especially when replacing lamps, since each lamp body has the same connection seat, the lamp body can be directly replaced without disassembling the fixing seat, which greatly simplifies the replacement process.

Detailed ways

In order to make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be clearly and completely described below with reference to the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

FIG. 1 schematically shows the structure of a fixing base 1000 according to an embodiment of the present application in a top view. FIG. 2 is an exploded schematic view of FIG. 1 . FIG. 7 schematically shows a perspective view of the first body part 1 . As shown in FIG. 1 , FIG. 2 and FIG. 7 , the fixing base 1000 includes a first main body part 1 and a junction box 200 detachably installed in the first main body part 1 .

Specifically, the first body portion 1 includes a bottom end plate 100 and a side wall 104 . In one embodiment, the sidewalls 104 are circumferentially distributed vertical sidewalls. The bottom end plate 100 and the side wall 104 enclose a accommodating cavity 101 , and the surface of the bottom end plate 100 enclosing the accommodating cavity 101 is the bottom end surface 100A. Viewed as a whole, the accommodating cavity 101 is generally in the shape of a basin. Of course, the bottom end plate 100 can also be of other shapes, as long as it forms the accommodating cavity 101 together with the side wall 104 , which will not be repeated here. At the same time, the first main body part 1 is also provided with a first detachable connection part for directly detachable connection with the junction box, which will be described in detail below.

The junction box 200 has a first electrical connection portion 2021 . At the same time, the junction box 200 is also provided with a second detachable connection part for detachably matching with the first detachable connection part, and the structures of the first detachable connection part and the second detachable connection part are configured to be able to pass through The detachable connection is realized in the manner of relative rotation along a rotation axis, and through the detachable connection, the junction box 200 can be detachably fixed in the accommodating cavity 101 . In order to reduce the overall thickness of the fixing base 1000 , the junction box 200 is usually attached to the bottom end plate 100 , so the rotation axis is preferably arranged perpendicular to the bottom end plate 100 .

After the junction box 200 in this embodiment is fixed in the accommodating cavity 101 , the first electrical connecting portion 2021 thereof may face the opening of the accommodating cavity 101 or be away from the opening of the accommodating cavity 101 . When the first electrical connecting portion 2021 faces away from the accommodating cavity 101 When the cavity 101 is opened, a mounting through hole 102 communicating with the accommodating cavity 101 may be provided on the bottom end plate 100 to expose the first electrical connection portion 2021 to the outside. In this embodiment, the first detachable connecting portion and the second detachable connecting portion may adopt various matching structures, which will be described below with examples.

When the bottom end plate 100 is provided with the installation through hole 102, the junction box 200 can be provided with the second connection portion 202 to be detachably installed at the installation through hole 102, and the first electrical connection portion 2021 can be installed through the installation through hole 102. The hole 102 is outside the receiving cavity 101 (as shown in FIG. 7 ). Thereby, the junction box 200 is detachably mounted in the first main body portion 1 .

As shown in FIG. 2 , FIG. 3 and FIG. 8 , the mounting through hole 102 is circular, the cross-sectional shape of the second connecting portion 202 is also circular, and the diameters of the two are matched. In this way, after the junction box 200 is installed at the installation through hole 102, the orientation of the junction box 200 can be rotatably adjusted, thereby further facilitating the user to complete the wiring operation. It should be understood that the diameter of the second connection portion 202 and the diameter of the installation through hole 102 can be determined by the principle of tolerance fit, so that the second connection portion 202 can be smoothly installed in the installation through hole 102 .

Specifically, the second detachable connecting portion may be configured with an extension portion 205 extending radially outward on the circumferential outer side of the second connecting portion 202 , and at least two notches 206 are configured on the extending portion 205 . The first detachable connecting portion can be designed as a claw 105 constructed around the installation through hole 102 , the claw 105 is matched with the notch 206 , and a clamping gap can be formed between the claw 105 and the bottom end surface 100A. The extension portion 205 enters the clamping gap through the notch 206 , and then the notch 206 and the claws are staggered by relative rotation along the rotation axis, so that the extension portion 205 can be clamped with the claws 105 . In this way, when assembling, align the notch 206 on the extension part 205 with the claw 105, the extension part 205 will be around the installation through hole 102 and the second connecting part 202 will be aligned with the installation through hole 102; then rotate the second The connecting portion 202 (or the junction box 200 ) makes the claws 105 deviate from the notch 206 to snap together with the extension portion 205 , as shown in FIG. 9 . This rotation and snap-fit assembly method is very simple, and it is convenient for the user to quickly complete the assembly of the first main body portion 1 . Preferably, a plurality of claws 105 can be arranged in the circumferential direction, for example, two. In the radial direction, the two claws 105 are arranged radially opposite to each other, and the two notches 206 are correspondingly arranged radially opposite, which can simplify the notches 206 and the design of the jaw 105.

Preferably, as shown in FIG. 3 , the extension portion 205 includes a bevel guide area 207 and a fastening area 208 . The inclined surface guide area 207 is adjacent to the notch 206 , the fastening area 208 is smoothly engaged with the inclined surface guide area 207 , and the fastening area 208 can be fixedly engaged with the claws 105 . In this way, under the guidance of the inclined surface guide area 207, the second connecting part 202 can be rotated more smoothly and the fastening area 208 and the clamping claw 105 can be snapped together, so that the junction box 200 can be connected to the first main body part more smoothly. 1 assembled together.

More preferably, an abutting surface may be formed on the junction box 200, for example, the side surface of the extension portion 205 facing the bottom end surface 100A, when the inclined surface guide area 207 is located in the clamping gap, the abutting surface abuts against the bottom end surface 100A. , and at this time, the side of the fastening area 208 facing away from the bottom end surface 100A is flush with the side of the clamping claw 105 facing the bottom end surface 100A or further away from the bottom end surface 100A. In this way, only the junction box 200 needs to be rotated, so that the clamping claw 105 can be tightly engaged with the fastening area 208, thereby further simplifying the assembly process. Still preferably, as shown in FIG. 3 , the inclined surface guide area 207 is only located on one side of the notch 206 . In this way, the junction box 200 can only be turned in one direction to engage it with the bottom end plate 100, while turning the junction box 200 in the opposite direction will allow it to be separated from the bottom end plate 100, which is required for the lead part 201 In the case of a specific direction, it is a foolproof structure, which further facilitates the assembly of the first main body part 1 .

Therefore, when a user performs a wiring operation, the junction box 200 is first removed from the mounting through hole 102 . After the cable is connected to the junction box 200 , the junction box 200 is installed into the installation through hole 102 . In this way, the wiring operation will not be restricted by the accommodating cavity 101 of the first main body part 1, which greatly facilitates the wiring operation. In addition, the remaining space of the accommodating cavity 101 can also be used as a cable hiding space, so as to hide redundant cables in the accommodating cavity 101 . In one embodiment, in the radial direction, the ratio of the length of the junction box 200 to the radius of the bottom end plate 100 is less than or equal to 1:2. In this way, the space for the wiring operation is larger, so that the user can conveniently complete the wiring operation.

As shown in FIG. 2 , a baffle plate 106 is provided between the adjacent claws 105 , and the extension portion 205 of the junction box 200 abuts against the baffle plate 106 . The baffle 106 can block the extension portion 205 from disengaging from the clamping claw 105, thereby improving the assembly stability. In addition, in the case where a specific orientation of the lead portion 201 is required, the baffle 106 is also used to assist in determining the orientation of the lead portion 201 , which further facilitates the assembly of the first body portion 1 . In a preferred embodiment, the baffle 106 is arc-shaped and extends along the circumference of the mounting through hole 102 .

FIG. 4 schematically shows another way of assembling the junction box 200 and the first main body part 1 . As shown in FIG. 4 , an internal thread 1020 is formed on the installation through hole 102 , and an external thread 2020 matching the internal thread 1021 is formed on the peripheral outer wall of the second connecting portion 202 . Therefore, the second connection portion 202 and the installation through hole 102 are connected by a screw thread, that is, the junction box 200 is connected with the first main body portion 1 by a screw thread, and the orientation of the terminal box 200 can be rotatably adjusted.

In this embodiment, the axis of the installation through hole 102 and the rotation axis of the junction box 200 can be coaxially arranged, so that the junction box 200 does not eccentrically displace relative to the installation through hole 102 during rotation and can maintain its own position.

For the solution in which the mounting through hole 102 is not provided on the bottom end plate 100, the above-mentioned matching structure of the claw 105 and the extension part 205 or the matching structure of the inner thread 1020 and the outer thread 2020 can still be used, and these structures do not need to surround The installation through holes 102 are provided, and the arrangement position of the first electrical connection part 2021 in this solution is generally opposite to the above solution, that is, the first electrical connection part 2021 is located on the side of the junction box 200 away from the bottom end surface 100A.

As also shown in FIG. 3 , the junction box 200 further includes a lead portion 201 , and the lead portion 201 is located in the accommodating cavity 101 of the first main body portion 1 . The lead portion 201 is used to connect with the cable. The second connecting portion 202 is detachably installed at the installation through hole 102 , preferably is assembled after rotation, and can be disassembled after reverse rotation. Since the first electrical connection part 2021 and the second connection part 202 are in an integral structure, during assembly, only the second connection part 202 is installed in place to ensure that the first electrical connection part 2021 is located at the bottom end plate through the installation through hole 102 100 outside. This eliminates the need to pay special attention to the assembly state of the first electrical connection portion 2021 , which facilitates the assembly process of the first main body portion 1 .

5 and 6 show the internal structure of the junction box 200 . As shown in FIGS. 5 and 6 , the junction box 200 includes a box cover 250 that is fastened together and a wiring module 210 disposed in the box cover 250 .

The connection terminal 211 is located in the lead portion 201 , and the electrode 212 forms an electrical connection device of the first electrical connection portion 2021 . In the use state of the first main body part 1, the external cables are electrically connected with the connection terminal 211 (for example, by at least two cables, including the live wire and the neutral wire; in other preferred embodiments, there may be three cables , including live wire, ground wire and neutral wire), and supply power to the lamp through the connection terminal 211 and the first electrical connection part 2021. Since the wiring module 210 is a complete circuit module, in the wiring operation, it is only necessary to electrically connect the cable and the wiring terminal 211 together, thereby simplifying the wiring operation. In a specific embodiment, there are three connection terminals 211 and three corresponding electrodes 212 on the connection module 210 . The three connection terminals 211 can be respectively connected with the corresponding three cables. For example, the three cables are the live wire, the ground wire and the neutral wire, the three connection terminals 211 are the positive terminal, the negative terminal and the ground terminal, and the three electrodes 212 are correspondingly the positive terminal, the negative terminal and the ground terminal. In other embodiments, there are two connection terminals 211 and two corresponding electrodes 212 . The two connection terminals 211 can be respectively connected with the corresponding two cables.

With the lamp fixing device of the preferred embodiment of the present invention, the operator can quickly install and disassemble the lamp, so it is easy to use and easy to maintain.

Preferably, the lamp fixture 2000 further has an elastic element 2010, the elastic element 2010 is configured to exert an axial force and a radial friction force between the first body portion 1 and the connecting seat 2002, so as to avoid the assembled connecting seat 2002 There is a relative displacement with the first main body part 1 , that is, it is ensured that the connecting seat 2002 will not move up, down, left and right relative to the first main body part 1 after the installation of the lamp is completed. Further, as shown in FIG. 10 , the elastic element 2010 may be disposed on the bottom end surface of the first main body portion 1 of the fixing seat 1000 at a position close to the first joint portion, for connecting the first joint portion of the fixing seat 1000 to the first joint portion. When the second joint portion of the connecting seat 2002 is connected, an axial force is applied to the bottom end surface of the second receiving cavity. Further, the elastic element 2010 may also be disposed on the bottom end surface of the second receiving cavity of the connecting seat 2002 at a position close to the second connecting portion (not shown), for connecting the first connecting portion of the fixing seat 1000 to the connecting seat When the second joint part of 2002 is connected, an axial force and a radial friction force are applied to the bottom end surface of the first main body part of the fixing seat 1000 .

Preferably, as shown in FIG. 11 , the elastic element 2010 disposed on the bottom end surface of the first main body portion of the fixing seat includes an elastic portion 2011 and a pressing portion 2012. The pressing portion 2012 is fixedly connected with the elastic portion 2011. When the first main body portion 1 is connected to the connecting seat 2002, the elastic portion 2011 is pressed by the junction box 200, so that the pressing portion 2012 of the elastic element 2010 is pressed downward. The bottom end face of the cavity of the connection seat 2002, at this time, the elastic part 2011 is in a compressed state, and an axial force is generated between the first main body part 1 and the connection seat 2002 to ensure that the connection seat 2002 is installed after the lamp is installed. It does not move up and down, left and right with respect to the first main body part 1 . Further, the elastic element 2010 is evenly arranged at a position close to the first joint with the center of the bottom end surface 100A of the first main body portion 1 as the center of the circle, or the center of the bottom end surface of the second receiving cavity 2B of the connection seat 2002 is the center of the circle. Evenly arranged at the position close to the second joint. Further, the number of the elastic elements 2010 is consistent with the number of the first joint part or the second joint part, and the elastic elements 2010 and the first joint part and the second joint part are arranged in a straight line in the radial direction. Preferably, the number of elastic elements 2010 is three.

Preferably, the first joint portion of the first body portion 1 is at least two bumps 2003 disposed along the circumferential direction of the first body portion 1 . The second joint portion of the connection base 2002 is correspondingly at least two U-shaped installation grooves 2005 disposed along the circumference of the inner wall of the second receiving cavity 2B. The U-shaped installation grooves 2005 include an open end 2051 and a limiting structure 2052 . When the first main body part 1 is combined with the connecting seat 2002, the protrusion 2003 of the first main body part 1 is inserted from the open end 2051 of the U-shaped installation groove 2005, and rotates along the circumferential direction of the inner wall of the second receiving cavity 2B until it rotates When the limiting structure 2052 of the U-shaped installation groove 2005 is reached, the installation in place is realized, that is, the mechanical connection between the first joint part of the first main body part 1 and the second joint part of the connecting seat 2002 is completed.

Preferably, as shown in FIG. 10 , there is a height difference between the limit structure 2052 of the U-shaped installation groove 2005 and the open end 2051 , and the limit structure 2052 is higher than the open end 2051 . When installing the lamp, push up the connecting base 2002, overcome the axial force of the elastic element 2010 on the connecting base 2002, push the bump 2003 of the connecting base 2002 to the position near the open end 2051 of the U-shaped installation groove 2005, and then push the bump 2003 enters from the open end 2051 of the U-shaped installation groove 2005 , and rotates along the circumferential direction of the inner wall 2B of the second receiving cavity to abut against the inner wall of the limiting structure 2052 . Due to the presence of the axial force of the elastic element 2010 , the connecting seat 2002 will move axially away from the first main body part 1 until the top surface of the protrusion 2003 of the first main body part 1 is limited by the connecting seat 2002 The inner top surfaces of the structures 2052 are abutted so as to realize the mechanical connection between the first joint portion of the first main body portion 1 and the second joint portion of the connection seat 2002 . After that, between the first main body part 1 and the connection seat 2002, the axial force generated by the elastic element 2010 always exists, and under the action of the lamp's own gravity, the first main body part 1 and the connection seat 2002 are engaged with each other It is more stable, and the lamp will not shake up and down, left and right.

Preferably, the number of the second combining parts is in a multiple relationship with the number of the first combining parts, and the number of the second combining parts is not less than the number of the first combining parts. Specifically, the number of the first joint parts, such as the bumps 2003, is preferably three, and the number of the second joint parts, such as the U-shaped mounting grooves 2005, is six, and the three bumps 2003 are spaced at the same angle from each other. The six U-shaped mounting grooves 2005 are spaced at the same angle from each other. Through such a configuration, only a small angle of rotation is required to realize the mechanical connection between the first joint part of the first main body part 1 and the second joint part of the connection seat 2002. connection, making the installation and disassembly of the lamp quicker.

Preferably, the U-shaped mounting groove 2005 further has a triangular guide portion 2053 for guiding when connecting between the protrusion 2003 of the first main body portion 1 and the U-shaped mounting groove 2005 of the connecting seat 2002 . Specifically, the top of the guide portion 2053 faces the bottom end surface of the first main body portion 1 , and the two sides of the guide portion 2053 are small inclined surfaces. Under the guidance of the small inclined surfaces, the operator can quickly and accurately place the bump 2003 on the At the open end 2051 of the U-shaped mounting groove 2005, there is no need to clearly observe the relative position of the bump 2003 and the U-shaped mounting groove 2005 before performing alignment installation, so that blind mounting of the lamp can be realized only by hand.

Preferably, the U-shaped installation groove 2005 further has a hook portion 2054, which is a small inclined surface adjacent to the open end 2051 of the U-shaped installation groove 2005 and extending toward the bottom end surface of the second receiving cavity 2B. By providing the hook portion 2054, the operator needs to push up and then rotate the connecting base 2002 to remove the lamp when disassembling the lamp. Specifically, when the first main body part 1 and the connecting seat 2002 need to be separated, the operator cannot directly rotate the connecting seat 2002 in the opposite direction to separate the first main body part 1 and the connecting seat 2002 because the hooking part 2054 In the presence of the hooking portion 2054 , the protruding block 2003 can be blocked from being directly moved out of the U-shaped mounting groove 2005 . At this time, the operator needs to push up the connecting seat 2002 first. Since the positions of the first main body 1 and the bump 2003 are fixed, the upward movement of the connecting seat 2002 will cause the top surface of the bump 2003 to be attached to each other and the U-shape. The inner top surfaces of the limiting structures 2052 of the installation groove 2005 are separated from each other, and the open end 2051 of the U-shaped installation groove 2005 is also moved to a position equal to the height of the bump 2003, and then the connecting seat 2002 is rotated in the opposite direction to Realize the disassembly of lamps. This configuration of pushing up and then rotating the connecting base 2002 before disassembling the lamp reduces the possibility of the operator disassembling the lamp due to misoperation, reduces the possibility of danger caused by children disassembling the lamp without permission, and improves the relationship between the first main body part 1 and the first main body part 1. The connection stability between the connection bases 2002 and the electrical safety of the lamps.

In this embodiment, the second electrical connection portion 2111 of the connection base 2002 includes the same number of conductive terminals as the receiving grooves on the first electrical connecting portion 2021 from the inside to the outside along the rotation axis, and the positions of the conductive terminals and the receiving grooves are one by one. correspond. When the first electrical connection portion 2021 is matched with the second electrical connection portion 2111, the conductive terminal can extend into the corresponding receiving groove to realize electrical connection. Preferably, as shown in FIG. 10 and FIG. 12 , the second electrical connection portion 2111 of the connection base 2002 includes a first conductive terminal 2061 , a second conductive terminal 2062 and a third conductive terminal 2063 which are sequentially distributed from outside to inside. When the first joint part of the first main body part 1 is connected to the second joint part of the connection base 2002 , the first conductive terminal 2061 , the second conductive terminal 2062 and the third conductive terminal 2063 are respectively accommodated in the first receiving groove 41 , the second conductive terminal 2063 The second accommodating grooves 42 and the third accommodating groove 43 are electrically connected to the electrodes in the accommodating grooves, so as to realize the electrical connection between the first electrical connecting portion 2021 of the junction box 200 and the second electrical connecting portion 2111 of the connecting seat 2002 . Further, the first conductive terminal 2061 and the second conductive terminal 2062 are metal rings which are respectively adapted to the size and shape of the first receiving groove 41 and the second receiving groove 42 , and the third conductive terminal 2063 is compatible with the third receiving groove. 43 Metal pins that are sized and shaped to fit. Through the arrangement of the annular electrical connection, the distance between the first receiving groove 41 , the second receiving groove 42 and the third receiving groove 43 and the first conductive terminal 2061 , the second conductive terminal 2062 and the third conductive terminal 2063 is increased. The contact area enables the first electrical connection portion 2021 and the second electrical connection portion 2111 to be electrically connected in any relative rotational orientation. At the same time, the first insulating portion, the second insulating portion and the third insulating portion The conductive terminal 2061 , the second conductive terminal 2062 and the third conductive terminal 2063 are completely insulated from each other, thereby improving the safety of electricity use.

Preferably, as shown in FIG. 10 , the first main body part 1 is formed with a mounting support 2007 protruding outward from its upper end edge, and the first main body part 1 is connected to a ceiling or a base body such as a ceiling through the mounting support 2007 connect. Specifically, the mounting support 2007 is provided with a number of screw holes for screwing with the ceiling or the ceiling.

Preferably, as shown in FIG. 12 , the second main body portion 2A of the connecting base 2002 is formed with a circular bearing portion 2008 protruding outward from its upper end edge, and the lamp is connected to the connecting base 2002 through the annular bearing portion 2008 .

As shown in FIG. 17 , in the lamp 1700 including the lamp fixing device 2000 provided by the embodiment, the fixing base 1000 is an independent part, and the connecting base 2002 can be detachably connected with the lamp body 1701 , or can be integrated with the lamp body 1701 Moreover, the second joint part in the connection seat 2002 can be integrated on the second main body part 2A, and when the connection seat 2002 is integrally connected with the lamp body 1701, the second electrical connection part 2111 can also be set independently Way. For example, the second joint portion and the second electrical connection portion 2111 may be directly and independently provided at different positions of the lamp body 1701 without the second main body portion 2A.

The present invention will be further elaborated below through a specific installation example:

First, strip the pre-wired wires on the ceiling or the wall respectively, the stripping length is preferably 8-10mm, then press the switch button corresponding to each electrode on the first main body part 1, insert the corresponding wires respectively, and then pass the installation support 2007 The first main body part 1 can be fixed on the ceiling or the ceiling by using several screw holes on the ceiling to screw the ceiling or the wall.

Next, align the connection seat 2002 with the center of the first main body portion 1 , push the connection seat 2002 up, so that the first conductive terminal 2061 , the second conductive terminal 2062 and the third conductive terminal 2063 are respectively accommodated in the first receiving groove 41 and the second conductive terminal 41 . in the accommodating groove 42 and the third accommodating groove 43 .

Finally, the connecting seat 2002 is rotated so that the protrusions 2003 of the first main body part 1 are inserted from the open end 2051 of the U-shaped installation groove 2005, and rotated along the circumferential direction of the inner wall of the second receiving cavity 2B until it reaches the U-shaped installation groove. The 2005 limit structure 2052 is installed in place.

Since the bumps 2003 are engaged in the U-shaped mounting grooves 2005, and the axial force of the elastic element 2010 and the effect of the weight of the lamp itself, the connection between the first main body 1 and the connecting seat 2002 is more stable, thereby realizing Mechanical connection of lamps.

Fig. 13 schematically shows the first body part 1 according to another embodiment of the present application. As shown in FIG. 13 , the first main body 1 is provided with a mounting support 2007 in order to connect with the base such as the ceiling. We call the contact surface between the first main body 1 and the base as the top surface. The top surface can be a virtual plane and is connected to the first The bottom end surface 100A of the main body portion 1 is facing each other. It can be seen from FIG. 13 that in this embodiment, the mounting support 2007 is located on the outer side of the upper end edge or the top end surface of the first main body portion 1 , and the mounting support 2007 is formed to extend outward along the upper end edge of the outer surface of the first main body portion 1 , The upper surface of the mounting bracket 2007 is flush with the top surface of the first main body portion 1 . There are a plurality of mounting supports 2007, which can be connected to the base body by connecting parts such as screws or integrally formed with the first main body 1. After the installation of the lamp is completed, the mounting supports 2007 actually carry the weight of the entire lamp, so in this embodiment A first reinforcing plate 3061 is provided in the mounting support 2007 as a first reinforcing structure. The first reinforcing plate 3061 is a substantially L-shaped sheet metal plate, which can be formed by stamping or bending from the metal plate. The mounting bracket 2007 is provided with an installation position that can accommodate the first reinforcing plate 3061. When connecting the first main body 1 and the base body, the screws pass through the mounting bracket 2007 and the first reinforcing plate 3061 in turn and are fixed to the base body. The first reinforcing plate 3061 in the seat 2007 can play a reinforcing role to prevent the installation support 2007 from being broken and improve the safety. The mounting support 2007 is provided with a concave receiving space along its upper surface, and the first reinforcing plate 3061 is received therein. The combination of the two can be assembled or overmolded into one.

In this embodiment, the first joint portion is a protrusion 2003 protruding outward from the lower end edge of the outer surface of the first main body portion 1. In the assembled state, the first joint portion will bear a large external force. The second reinforcing plate 3062 is set at the part as the second reinforcing structure, and the second reinforcing plate 3062 is also a metal plate. In other preferred embodiments, the second reinforcing plate 3062 can also be inserted into the inside of the first joint portion, or overmolded into one piece.

As mentioned above, although the mounting bracket 2007 and the first joint portion are more reliable due to the addition of the reinforcing structure, the force of the lamp hanging on the first main body portion 1 still needs to pass through the first main body portion 1 to be transmitted to the base , so we add a connecting plate 3063 between the first reinforcing plate 3061 and the second reinforcing plate 3062, and the two ends of the connecting plate 3063 connect the first reinforcing plate 3061 and the second reinforcing plate 3062 respectively, making it a single The reinforcing member 3006 is shown in Fig. 14 for the structural schematic diagram of the reinforcing member. In this embodiment, since the first reinforcing plate 3061 and the second reinforcing plate 3062 are both metal plates, the reinforcing member 3006 can be formed by bending a whole piece of metal sheet, and other high-strength materials can also be used in other embodiments. to make reinforcement 3006. 15 is a cross-sectional view of the reinforcing member 3006 after being installed in the first main body portion 1. In order to realize the installation of the reinforcing member 3006, the number of the first joint portion and the number of the installation supports 2007 should be the same, and the number of the first joint portion should be the same as that of the installation support 2007, and the first A joint portion and the mounting support 2007 face each other in the axial direction. For the connecting plate 3063, firstly, a through groove needs to be opened at the first main body portion 1 to accommodate the connecting plate 3063, and the connecting plate 3063 passes through the through groove to make the outside of the mounting seat smooth. In other preferred embodiments, the connecting plate 3063 can be attached to the outer surface of the first main body portion 1 and connected to the first main body portion 1 by connecting elements such as screws and clips.

After adding the reinforcing member 3006 to the first main body portion 1, we also add a reinforcing structure to the connecting seat 2000. Please refer to FIG. 16 for details. The second main body portion 2A of the connecting seat 2000 is provided with a reinforcing bracket 3206. Pass through the second main body portion 2A of the connecting seat and the reinforcing bracket 3206 at the same time. The reinforcing bracket 3206 can be disposed on the connecting base 2000 or can be integrally overmolded with the connecting base 2000 .

In addition, when the lamp installation device of the present application is used to install the lamp, since the connection between the first main body part 1 and the connection base 2000 is achieved by rotation, which is unfavorable for the square lamp, the outer frame of the lamp cannot be kept horizontal with the wall, which affects the overall effect. Therefore, we set a positioning structure on the first main body portion 1 . The positioning structure includes four positioning pieces extending outward from the first main body portion 1 , and the positioning pieces are evenly distributed on the circumference centered on the rotation axis of the connecting seat 2000 . In this embodiment, we directly arrange the four mounting supports 2007 as positioning members, and the included angle between the two adjacent mounting supports 2007 is 90 degrees. In other embodiments, the number of mounting supports 2007 may not be four, but in order to achieve positioning, there should be at least four mounting supports 2007. When there are more than four mounting supports 2007, four of them can be selected for positioning As a positioning structure, the mounting bracket 2007 can be distinguished from other mounting brackets 2007 in appearance (shape or color).

Next, we will explain the specific steps in the installation of the lamp in this embodiment. In this embodiment, the lamp installation device is used to install a square lamp:

The external power cord is connected to the first electrical connection part.

The connection seat 2000 has been pre-set on the lamp, the connection seat 2000 is installed in the first main body part 1, and the connection seat 2000 is rotated clockwise, and the second joint part on the connection seat 2000, that is, the installation slot 2005 is also rotated to the first joint part. That is, the bump 2003 is located at and suspended on the bump 2003 . Keep the lifting state slowly downward, confirm that the installation groove 2005 is effective, and the installation groove 2005 of the connecting base 2000 and the bump 2003 of the first main body 1 are securely assembled without loosening, and the installation process is completed.

The mounting support 2007 of the first main body part 1 acts as a positioning structure, and the connection line of a pair of mounting supports 2007 arranged opposite is either perpendicular to the reference wall, or parallel to the reference wall, and two adjacent mounting supports 2007 The included angle is 90 degrees. Since the number of the first joint parts is the same as that of the installation supports 2007, there are 4, and there are also 4 connection directions of the connection seat 2000 and the first main body part 1, but the connection seat 2000 is connected to the first The main body part 1 can be assembled so that the side wall of the square lamp can be kept parallel to the reference wall.

In one embodiment, as shown in FIG. 1 , each mounting support 2007 is provided with a waist-shaped hole 111 . When installing the light fixture, the first main body part 1 is fixed to the ceiling through the mounting bracket 2007 and the waist-shaped hole 111 .
